About Schultenite

Schultenite is an extremely rare lead hydrogen arsenate mineral that forms colorless to white tabular crystals with a vitreous to adamantine luster in the oxidation zones of lead-arsenic ore deposits. First described in 1906 from Tsumeb, Namibia, which remains one of its only known localities, it is primarily a mineralogical curiosity. Its rarity and the toxic nature of its chemical composition make it strictly a collector's mineral.
